The present disclosure relates to a solid-state image sensor, driving method, and electronic apparatus, capable of achieving reduction in pixel size and sensitivity improvement. The solid-state image sensor includes a PD configured to convert light into electric charge by photoelectric conversion and to store the electric charge, a first transfer transistor configured to read out the electric charge stored in the photoelectric conversion unit, a multiplication region configured to store temporarily and multiply the electric charge read out through the read-out unit, and a second transfer transistor configured to transfer the electric charge stored in the multiplication region to a conversion unit configured to convert the electric charge into a pixel signal. Then, an intense electric field is generated in the multiplication region to multiply electric charge by the avalanche effect in transferring the electric charge from the multiplication region to an FD portion through the second transfer transistor. The present technology is applicable to, in one example, the stacked CMOS image sensors.

HDR imaging

The present disclosure generally relates to HDR imaging techniques, and more specifically to HDR imaging techniques for use when a scene is moving. For time delay integration, the same scene location is repeatedly imaged on sequential rows, allowing for different gain values and/or exposure times to be utilized in different rows. The present disclosure utilizes a static or dynamic selection of gain values and/or exposure times on each row to enable stitching of the rows for high dynamic range.
